HEATER.

SPECIFICATION forming part of Letters Patent No. 568,852, dated October 6, 1896. Application filed May 5,1896. Serial No. 590,321. (No model.)

To all whom it may concern:

Be it known that I, ZACHARIA DAVID` JOHNS, a citizen of t-heV United States, residing at Visalia, Tulare county, State of California, have invented certain-new'and useful Improvements in Heaters, of which the following is a specification.

This invention relates to certain new' and useful improvements in Water-heaters; and it consists in the combination, arrangement, and construction of the parts hereinafter more particularly referred to.

In the accompanying drawings, forming a part of this specification, andin which like letters and numerals of reference indicate corresponding parts, Figure l is a vertical longitudinal sectional View of the heater. Fig. 2 is a horizontal sectional View on the line xof Fig. 1. Fig. 3 is a vieW showing the parts separated, and Fig. Liis a vertical longitudinal sectional View of a modification of the'invention.

Referring more particularly to the drawings, A designates the casing of the heater, formed of any suitable material,such as sheetiron, dac., and comprising a central cylindrical section B, a bottom section C, and a top section D, said sections being detachably connected. This casing is supported in any suitable manner upon a stove or furnace E and communicates with the fire-space thereof. The bottom section of thecasing is provided With an inlet-opening located preferably at one side thereof, and around this opening is a collar l, adapted to fit over a flange which surrounds an opening 2, through Which the Waste products of combustion escape from the stove to the stovepipe. This bottom section is also provided with a draft-opening 3, controlled by a suitable valve, consisting in the present instance of a slide 4f, and by means Lof this opening the temperature of the heater maybe regulated. The opening 3 also serves to permit the Withdrawal of al1 soot and dust Whichl may accumulate in the bottom of the heater.

Extending centrally throughout the length of the central section B is a heat absorbing and radiating cylinder F, formed of sheet-iron or of some suitable refractory'material. This cylinder is provided at its loWer end with a conical cap 5, the end of which extends to a plane at one side of the plane of the axis of .the cylinder to bring it directly over the opening 2, and this end of the cap is provided With an opening through which communication may be had With the interior of the cylinder F, which in turn is open at its upper end to permit the free passage therethrough of the products of combustion. The cylinder F is of less diameter than the central section B, and is supported Wholly upon either the top or bottom sections in any suitable manner, as shown in Figs. l to 3. Said cylinder is supported upon the bottom section by means of an arm 6, and in Fig. 4. itis shown supported Wholly upon the top section.

Within the casing and supported preferably upon the central section B is a coil-pipe G, through which the Water to be heated is circulated. The coils of this pipe surround the heat absorbing and radiating cylinder F and are in close proximity thereto, and the ends of the coil are connected to a suitable reservoir or to the circulating-pipes of a heating system.

The top section D of the casin g is provided with a discharge-opening surrounded by a flange 7, to which is adapted to be fitted asection of the stovepipe, which conducts the products of combustion to the open air.

In addition to serving as a radiator and deilector the cylinder F also serves as aconveyer for the dirt and soot, and to this end the opening in the upper end of the cylinder is formed as large or larger than the dischargeopening and is in alinement therewith, in consequence of Which the dirt or soot which drops from the stovepipe into the cylinder F is conveyed to the inlet-opening 2, through which it passes back into the stove.

Of course it Will be understood that soot Will collect Within the casing upon the coilpipe and upon the exterior of the cylinder F, and in order to remove this it is only necessary to detach the bottom section O from the central section B and remove the cylinder from Within the coil-pipe, as shown in Fig. 8, thereby rendering the cylinder and the coil readily accessible for cleaning.

From the above it Will be apparent that the products of combustion from the stove or furnace pass into the casing through the opening 2 and heat the coil G and cylinder F, a portion of the products of combustion passjecting ribs or plates S, which serves to deilect the hcatinto contact With the coil-pipe. In this form of heater the cylinder F is supported upon the top section D by means of arms 9.

That I claim isl. In a water-heater, the combination with the casing having inlet and discharge openings, of a circulatingpipe within the casing and an open-ended deflecting and conveying cylinder within the casing, the ends of which aline with the inlet and discharge openings of the casing, substantially as described.

2. In a water-heater, the combination with the easing having inlet and discharge openings, of an open-ended deiiecting and conveying cylinder` within Ithe casing, formed conical at its lower end, the ends oi the cylinder alining with the inlet and discharge openings of the casing, and a coiled circulating-pipe surrounding the said cylinder, substantially as described.

In a Water-heater, the combination with a sectional casing formed with inlet and discharge openings, the sections of said easing being detachable, of a heat deliectin g and radiating body within the casing supported wholly upon one of the sections thereof and a circulatingpipe also arranged within the casing and supportedwholly upon a section different from that which supports the said radiating and deiiecting body, substantially as described.

ll. In a Water-heater, the combination With a closed casing comprising a central section, a top section provided with a discharge-open ing and a bottom section having an inletopening, of a defiecting and radiating body provided With a eonicalend arranged to aline with the inlet-opening, said radiating body being supported wholly upon one of the scctions of the casing, and a circulating-pipe coiled around the radiating body and supported Wholly upon a section of the casing different from that which supports the radiating body, substantially as described.

5. In a Water-heater, the combination with a closed easing provided at its top with a central discl1argeopening and W ith an i11let1opeii ing located at one side of its bottom, of an open-ended radiating and conveying cylinder alining With the discharge-opening atits upper end and at its bottom provided With a conical cap extending laterally into alinelnent with the inlet-opening, and a circulating-pipe coiled around the cylinder, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
